Short term evaluation of total hip arthroplasty; our experience at tertiary care center
JPMA. The Journal of the Pakistan Medical Association, 2015
Total hip arthroplasty is a common and successful treatment for osteoarthritis of the hip. Demographic trends in Pakistan suggest a significant increase in the demand for total hip replacement surgery. The current study was planned to assess the outcome of THA at our centre in terms of pain relief and functional improvement by using pre and postoperative HHS. It was observed in this study that the functional outcomes were highly encouraging. Patients were handicapped because of pain, loss of movements and inability to carry out day-to-day activities due to arthritis of the hip joint. The same functional improvements were noted from examination of the patients according to Harris Hip Score. The descriptive case series was conducted at Punjab Medical College and affiliated hospitals from July 2013 to July 2014, and comprised patients of either gender 25 years or more of age with primary or secondary OA of hip. Severe complications in total hip replacement comprise dislocation, aseptic...
A study of uncemented total hip replacement in various hip disorders
International Journal of Orthopaedics Sciences, 2018
Background: Osteoarthritis (OA) is a major cause of disability among elderly population. It is a major cause of a burden on the health system and its incidence and prevalence continues to rise with a rapidly increasing aging population. Total hip replacement is considered one of the most important and successful intervention in the recent era. The study aims to determine the functional outcome and the complications associated with uncemented total hip replacement using modular prosthesis. In this study 32 cases with osteoarthritis of hip joint were treated by uncemented total hip replacement at Katuri medical college and hospital, China kondrupadu, Guntur between June 2015 to November 2016 were included. The functional outcome is assessed and compared with other studies. The aim of procedure is to assess the functional outcome of uncemented total hip replacement. Materials and Methods: Our study is prospective study of clinical and radiological analysis of uncemented total hip arthroplasties performed for various hip disorders. All patient data and clinical history were noted with reference to pain, range of motion, gait, activities or function (Harris Hip Score). Cementless acetabular components, cementless femoral components are used in this study. Results: All 32 patients in the present study returned for clinical and radiological examinations subsequently. Patients were reviewed after 6 weeks, 3 months, 6 months and 1 year post operatively. The age ranges from 32-60 years with mean age of 48.31 years. Most of the cases are between the age group of 51-60 years constituting 46.88% of study population. Of the 32 cases, male patients 22 constituting 68.75% and the rest 10 are female patients constituting 31.25% of the cases. Conclusions: Our study supports the usge uncemented THR in osteoarthritis in both young and elderly. The current trend, research and advent of new implants support uncemented THR in patients suffering from this crippling hip arthritis and avascular necrosis.

Total hip arthroplasty (THA) is one of the most common orthopedic surgeries (1). Pioneered by Sir John Charnley, THA has become a widely accepted surgical practice owing to advances in design and metallurgy, a better understanding of biology, and novel surgical techniques. The initial cemented THA prosthetic applications were associated with problems such as intraoperative hypotension, sudden death, aseptic loosening, and periprosthetic bone loss in young patients (2,3). This has led researchers to seek new designs, and uncemented prosthetics are widely preferred (4). Both cemented and uncemented designs have their own sets of advantages and disadvantages. This study aimed to compare the clinical and radiological outcomes of cemented, uncemented, and hybrid THA applications. MATERIAL AND METHODS The study was designed as a single-center and retrospective trial. Patients who underwent THA between April 1995 and December 2001 at the Tepecik Training and Research Hospital were included in the study. All the researchers who participated in the study signed the most recent version of the Helsinki Declaration. The informed consent form was obtained from the patients in the study. During the indicated time frame, 53 total hip arthroplasties were performed in the center on 48 patients. Patients followed up for at least 2 years were included in this study. Seven of the surgical patients opted out of follow-up, while 20 patients were excluded from the study due to insufficient follow-up time. Therefore, 23 total hip arthroplasties of 21 patients were evaluated in the study.
Outcomes following total hip arthroplasty: A review of the registry data
Indian Journal of Orthopaedics
While total hip arthroplasty remains one of the most reliable procedures with excellent, cost-effective outcomes, there remains controversy in the choice of implant in terms of method of fixation, bearing surface, and size of the femoral head, especially in the younger population. This review looks at the possible information base that surgeons can explore before choosing the implant that they are comfortable with. It also looks at the findings of various registries, which readers can use in the process of informed consent. We have provided certain recommendations with specific reference to the method of fixation, bearing surface, and head size that can be backed by the available registry data. However, the information provided should be used only after considering local, financial, and patient-specific issues that surgeons encounter on a daily basis during their practice.
Hip disease and the prognosis of total hip replacements
Journal of Bone and Joint Surgery-british Volume, 2001
W e studied the rates of revision for 53 698 primary total hip replacements (THRs) in nine different groups of disease. Factors which have previously been shown to be associated with increased risk of revision, such as male gender, young age, or certain types of uncemented prosthesis, showed important differences between the diagnostic groups. Without adjustment for these factors we observed an increased risk of revision in patients with paediatric hip diseases and in a small heterogeneous 'other' group, compared with patients with primary osteoarthritis. Most differences were reduced or disappeared when an adjustment for the prognostic factors was made. After adjustment, an increased relative risk (RR) of revision compared with primary osteoarthritis was seen in hips with complications after fracture of the femoral neck (RR = 1.3, p = 0.0005), in hips with congenital dislocation (RR = 1.3, p = 0.03), and in the heterogenous 'other' group. The analyses were also undertaken in a more homogenous subgroup of 16 217 patients which had a Charnley prosthesis implanted with high-viscosity cement. The only difference in this group was an increased risk for revision in patients who had undergone THR for complications after fracture of the femoral neck (RR = 1.5, p = 0.0005).
Primary total hip arthroplasty without the use of bone cement: a 10-year follow-up of 157 hips
Chang Gung Medical Journal, 2002
Background: The cementless fixation technique in total hip arthroplasty (THA) was developed to solve clinical problems such as aseptic loosening and osteolysis which were thought to be associated with the use of bone cement. This retrospective study reports our mid-term results with cementless THA. Methods: A series of 173 consecutive, unselected cementless THA procedures using the Omnifit prosthesis was performed by a single surgeon. Sixteen hips were excluded from the study because of insufficient follow-up evaluation. One hundred and fifty-seven THAs with an average follow-up period of 10.2 (range, 5-12) years were retrospectively reviewed. Results: The overall revision rate was 7.0%. Ninety-five percent of unrevised hips achieved a Merle D'Aubigne hip score of 16 points or above. Radiographically, bone ingrowth occurred in all unrevised cups, and in 95% of unrevised stems. Osteolytic lesions, seen on 28.1% of femora and 8.9% of pelvises, appeared at an average of 3.8 years postoperatively. Femoral osteolytic lesions were confined to the proximal Gruen zones 1 and 7. The mean annual polyethylene wear rate was 0.15 mm. Approximately 1/3 of the hips were noted to have excessive wear. Conclusion: These results suggest that cementless Omnifit THA provides stable fixation for as long as 12 years after implantation. Of significant concern is the high incidence of excessive polyethylene wear and associated osteolysis. Our experience also indicates that a femoral stem with a circumferential porous coating in the proximal region can protect the femur from distal osteolysis.
Long-term results of cemented total hip arthroplasty in patients 45 years old or younger
The Journal of Arthroplasty, 1994
Forty-nine cemented total hip arthroplasties in patients younger than 45 years were reviewed, with an average follow-up period of 16.2 years. The results were compared with the same group previously reported at average follow-up periods of 4.5 and 9.2 years. Clinically satisfactory results were 27% at 16.2 years compared with 78% at 4.5 years and 58% at 9.2 years. The revision rate increased from 12% at 4.5 years to 33% at 9.2 years to 67% in this study. The revision rate for patients younger than 30 at the time of the index arthroplasty was 82% compared with 56% for those over 30. Impending failure was present in 81% of the 16 unrevised hips compared with 56% at 9.2 years and 29% at 4.5 years. Patients younger than 30, in Charnley category A or B, dnd with a diagnosis of osteonecrosis or osteoarthritis had the poorest clinical results. As in the previous two studies, the best results were obtained in category C patients who were over 30 years of age with inflammatory collagen disease. The purpose of this study is to report the long-term (average, 16.2 years) follow-up results of patients under the age of 45 who underwent cemented total hip arthroplasty at Ranch0 Los Amigos Medical Center between 1972 and 1978. The 4.5-year and 9.2year results form the basis for comparison.
Good results with cemented total hip arthroplasty in patients between 40 and 50 years of age
Acta Orthopaedica, 2010
Background and purpose Total hip arthroplasties in young patients have lower long-term survival rates than in older patients. We evaluated the use of a unique treatment protocol in patients aged between 40 and 50 years. In all cases we used a cemented THA, and for acetabular deficiencies we also used impacted bone grafts together with a cemented cup.
